Dear R Staff

You can see my data.csv file in the annex.

I try to count non-zero values in dataset but I need to exclude NA in this
calculation

My code is very long (following),
How can I write this code more efficiently and shortly?

## [NA_Count] - Find NA values

data.na =sapply(data[,3:ncol(data)], function(c) sum(length(which(is.na
(c)))))


## [Zero] - Find zero values

data.z=apply(data[,3:ncol(data)], 2, function(c) sum(c==0))


## [Non-Zero] - Find non-zero values

data.nz=nrow(data[,3:ncol(data)])- (data.na+data.z)


Sincerely
Engin YILMAZ
